						    	<p><strong>What is Green Energy?</strong></p>
									<p>Green energy is a type of energy that produces energy with less negative impact on the environment compares to traditional energy sources like fossil and fuels. 
									 Some of the green energy sources are solar, wind and hydro energy. 
									 These energy sources are developed as alternative energy sources which do not produce greenhouse gases and have little or no impact on the climate change.</p>
						    	
						    	<p><strong>Solar Power</strong></p>
									<p>One of the great sources of green energy comes from the sun. The energy of sunlight can be transformed into heat and electricity. 
									There is almost no pollution generated in producing these types of energies. 
									Solar energy is cheap and available in most of the world, thus it can replace a large portion of fossil fuels like coal and oil and therefore lower the carbon dioxide emitted into the atmosphere. Solar energy can be used in houses, cities and even large space satellites. 
									solar energy can be generated by photovoltaic (PV) cells which convert sunlight energy directly into electricity. PV panels are made of many series of solar cells that are connected in a specific pattern to generate the maximum amount of energy. These PV panels can generate local energy for houses by installing them on top of a house’s roof. A large number of solar panels are mounted in solar farms for mass production.</p>
									
									
									<p><strong>Solar thermal collectors</strong></p>
									<img class="m2-image"src= "images/solar-power-car.jpg"width="240px" alt="Solar Power Car" title="Solar Power Car"/>
									
									<p>These collectors collect solar radiations’ heat. Solar thermal collectors are classified into three types low, medium, and high-temperature collectors.
									 Low-temperature collectors are used for heating pool in houses.
									 Medium-temperature types are used for heating water in houses and factories. 
									 Both types are flat panels that absorb the sun’s energy. 
									 High-temperature types are used in thermal power panels to generate electric energy.
									  These types increase the temperature of collectors by radiation are concentrated by many mirrors or lenses into a small area. 
									  This system is called concentrated solar power (CSP). 
									  CSP grew with an unprecedented speed during the last decade and is expected to continue growing at a fast rate all over world.</p>
								<p><strong>Good to know: positive effects</strong></p>
									<ul>
									<li>Without sunlight there is no life in earth</li>
									<li>Sunlight has a main role in vitamin D production</li>
									<li>Sunlight has psychological benefits such as preventing some type of depression</li>
									<li>Sunlight produces warmth</li>
									</ul>
									
									<p><strong>Good to know: Negative effects</strong></p>
									<ul>
									<li>Sunlight is a major cause of skin cancer</li>
									<li>Sunlight can produce serious skin damage</li>
									<li>UV light is a factor in developing aging spot</li>
									<li>UV light is a factor in skin aging</li>
									</ul>
						   	<p><strong>Good You Know:  Protect Yourself</strong></p>
						   	<ul>
								<li>Sun’s radiation is the strongest between 10 am and 4 p.m</li>
								<li>Wear sunglasses and use sunscreens</li>
								<li>	Keep very young children (6 months or less) out of the sun</li>
								<li>	To achieve adequate UV protection you should use production which cover both UVB and UVA rays </li>
								<li>According to the SSA, it is recommended to use sunscreen with an SPF 30 or higher for children </li>

								<p>Solar energy is a type of energy that comes from the sun. This energy can be converted into electricity and heat. Solar energy does not cause pollution or carbon dioxide therefore; it is safer for our environment. Solar power technology uses mirrors and receivers to collect the energy to convert into heat.  Low-temperature solar collectors collect heat from the sun and are used for heating offices and other buildings.</p>
